Lol, it is pretty funny.

I don't know if I'd leave them on there when running. That's a lot of weight to be bouncing on those sensitive FETs! BTW: why do you have a sink on the caps?? Caps should never get warm unless you are constantly charging and shorting them out, and that is simply from the current flow. The majority of the heat is most likely due to the FETs heating up, which heats the traces, which then travels to surrounding components (caps). Besides, caps, being round, don't have much surface area touching the sinks.

Like Serum said; it's not a bad job. If those don't keep it cool, the it's time to give up! :)

I got some runs in on my modified Quark this week before it rained. On two maxamps 8000's it ran for 23 minutes at full throttle (getting off it for the turns of course) around my oval track. The highest the fet area got was 137 f! It was the longest I have ever run my truck without having it thermal. Granted it was not 90 outside but full throttle for this length of time is about as hard as I can run it. Oh yeh no fans either.

The caps got up to 156 f so they do get hot even with air flowing over them.

Sorry for late responses, but looks like I need to get Quark for testing :)
